Small Pluton Construction by the Stacking and Differentiation of Magma Sheets: Insights from the Beauvoir Granite (Massif Central, France)

Nicolas Esteves, Lydéric France, Michel Cuney, Pierre Bouilhol Journal of Petrology, Volume 67, Issue 7, July 2026, egag055 Voir en ligne : https://doi.org/10.1093/petrology/egag055 Constraining the links between the assembly of granitic intrusions and their magmatic differentiation processes remains a major challenge in igneous petrology. Although it has been suggested that most granitic intrusions are emplaced

Advancing Last Glacial Maximum paleoclimate reconstructions in Europe using pollen data: a multi-method (mega)biomization approach

Gabriel Fénisse, Manuel Chevalier, Odile Peyron, David Vincent Bekaert, and Pierre-Henri Blard Climate of the Past Voir en ligne : https://cp.copernicus.org/articles/22/1507/2026/ Pollen records are among the highest-resolution spatial and temporal proxies for reconstructing past vegetation dynamics, environmental changes and climate variability. Over the past decade, a large variety of methods based on different ecological or

Experimental constraints on germanium diffusivity in metal and silicate phases during core formation of planetesimals and terrestrial planets

Baptiste Le Bellego, Celia Dalou, Béatrice Luais, Pierre Condamine, Vincent Motto-Ros, Laurent Tissandier Geochimica et Cosmochimica Acta 422: 397-411 Voir en ligne : https://doi.org/10.1016/j.gca.2025.11.038 The segregation of metallic cores from silicate mantles during early planetary differentiation is a key process shaping the chemical evolution of terrestrial bodies. A critical factor controlling metal-silicate equilibration during this stage

Nitrogen isotopic variations in the early Solar System recorded by pallasites

J. Gamblin, E. Füri, B. Luais, L. Zimmermann Geochemical Perspectives Letters v39 Voir en ligne : https://doi.org/10.7185/geochemlet.2607 To gain new insights into nitrogen (N) isotopic variations in the early Solar System, N and noble gas (Ne, Ar) isotopes were measured in metal fragments and olivine separates from thirteen pallasites and five IIIAB iron meteorites. While δ15N

Reactivation of a transcrustal plumbing system during a rifting event (Asal Rift, Djibouti)

Juliette Pin, Lydéric France, Gilles Chazot, Etienne Deloule, Mohamed Ahmed Daoud, Bernard Le Gall Geology (2026) 54 (4): 348–353. Voir en ligne : https://doi.org/10.1130/G53776.1 Magmatism plays a central role in rift dynamics, yet the structure and evolution of magma plumbing systems during continental break-up remain poorly constrained. The Afar Rift offers a rare opportunity to study
